Schedule

Ex Component(s) covered by this certificate is described below:

Subject and type

See Annex

Description

The motor protection circuit-breaker type 8523/8.-..-... is designed in type of protection flameproof enclosure "d" for the enclosure and in type of protection increased safety “e” for the connection terminals. It is used for the protection and switching of explosion protected electrical motors. The motor protection circuit-breaker is intended for installation into enclosures in type of protection increased safety “e” which are certified separately.

SCHEDULE OF LIMITATIONS:

After the installation of the motor protection circuit-breaker into an enclosure in type of protection increased safety "e", the clearances and creepage distances have to meet the requirements of 4.3 (fable 2) and 4.4 (fable 2) of IEC 60079-7.
